<p>PROBLEM TO BE SOLVED: To provide a garbage disposer with a structure that an earthworm hardly comes out and aeration is sufficiently performed. SOLUTION: A cross aeration layer 18 is laid on the bottom upper side of a box 4 of a garbage disposer 1 using an earthworm. A bottom part aeration hole 4n is installed corresponding to the outer peripheral side of the aeration layer 18. A lengthy board like aeration layer 20 which has gas permeability is arranged at the top of the upper side of the piece of the cross aeration layer 18. Thus, the outside air incorporated from the aeration hole 4n is introduced to the inside of the box 4 via the aeration layers 18, 20.</p> |
